(cherry picked from commit 4431cdd154b8fa0494148980646903e824c0bdb1)

|
The main change is to caculate tangent directly from bezier curve, without going
through discretized polyline, avoiding pitfalls of discretization. A similar refacor
had been applied to Curve3D.
The test cases for Curve2D is updated, comparing floating point with is_equal_approxmiate()
instead of `==`, in order to avoid float precision problem.
|
|
The problem is caused by calling adaptive tessellation baking function by mistake, which produce too few points for straight lines. Calling the even length tessellation fix the problem.
The code for `get_closest_point()` and `get_closest_offset()` are also updated. They used to assume bake interval to be exact, which is no longer true.
The out dated document for `get_closest_point()` is also updated.

The main change is to caculate tangent directly from bezier curve, without going
through discretized polyline, avoiding pitfalls of discretization.
Other changes are:
1. Add an bezier_derivative() method for Vector3, Vector2, and Math;
2. Add an tesselate_even_length() method to Curve3D, which tesselate bezier curve to even length segments adaptively;
3. Cache the tangent vectors in baked_tangent_vector_cache;

This commit makes the following major changes
1. Add "sample_baked_with_rotation()" to Curve3D, making it usable independently. A similar change was made to Curve2D previously.
2. Refactor the _bake() method on Curve3D, using Parallel Transport Frame instead of Frenet Frame.
3. Refactor the sample_* methods, including:
i. Factor out common binary search code, following the DRY principe
ii. sample_up_vector() interpolated up vector as part of rotation frame(posture) for consistancy and accuracy.

"sampling" is a more accurate term than "interpolating" for what's
happening when using that function.

Exposes the Curve, Curve2D and Curve3D points as an array property.

This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.
Each class XML's schema conformance is also checked on GitHub Actions.

For the time being we don't support writing a description for those, preferring
having all details in the method's description.
Using self-closing tags saves half the lines, and prevents contributors from
thinking that they should write the argument or return documentation there.

Based on the doc, I wasn't sure if get_closest_point would return the
closest baked point or the closest "source" point. It seems to use
baked:

|
The offset is in 3D units, not pixels.
This closes https://github.com/godotengine/godot-docs/issues/4339.

I verified this experimentally. I added a point at roughly (1,0,0), and
dragged a handle back to the origin. The result was:
```
get_point_position: (0.991079, 0, -0.000069)
get_point_in: (0.993409, 0, 0)
get_point_out: (-0.993409, 0, 0)
```

A few extra renames for classes which were missed in last week's PRs.

Handle removal of Pool*Array types and other recent changes.

We already removed it from the online docs with #35132.
Currently it can only be "Built-In Types" (Variant types) or "Core"
(everything else), which is of limited use.
We might also want to consider dropping it from `ClassDB` altogether
in Godot 4.0.

Thanks to @bojidar-bg's impressive work in #29380.

- Document a few more properties and methods
- Add more information to many classes
- Fix lots of typos and gramar mistakes
- Use [code] tags for parameters consistently
- Use [b] and [i] tags consistently
- Put "Warning:" and "Note:" on their own line to be more visible,
and make them always bold
- Tweak formatting in code examples to be more readable
- Use double quotes consistently
- Add more links to third-party technologies

It has no practical use case and just generates noise for each alpha, beta, etc.

Also enhance RigidBody docs as per https://github.com/godotengine/godot-docs/pull/1018
and fix the version tag in all files (not really stable yet, but it makes no sense
to hardcode rc3 at this stage).

It is now "3.0-alpha" instead of "3.0.alpha.custom_build{,.mono}",
limits unnecessary diffs.
|
|
Rename user facing methods and variables as well as the corresponding
C++ methods according to the folloming changes:
* pos -> position
* rot -> rotation
* loc -> location
C++ variables are left as is.

possible to save module files in module directories and the build system will
recognize them.
